CARRIAGE-WINDOW.

Specification of Letters Patent N. 4,433, dated March 21, 1846.`

To all whom t may concern f Be it knownthat we, JAMES OGDEN and D. R. HART, of Troy, in the county of Rensselaer and State of New York, have 1nvented several new and useful Improvements in Vindows, which improvements are applicable to cars, stages, and other carriages, and that the following is a full, clear, and exact description of the principle or character' thereof which distinguishes them from all other things before known and of the manner of making,` constructing, and using the same, reference being had to the accompanying drawings, making part of this specication, in Which- Figure l is a perspective View of the inside of a window of an omnibus; Fig. 2, a vertical section; Fig. 3, an outside view, and Fig. ll, a section of the window raised.

The same letters indicate like parts in all the figures.

The advantages resulting from our improvement are as follows: Experience has proved, that when a carriage is made with a recess for the window to slide down below the arm, the bodyis subject to decay from the effect of the dampness, occasioned by water leaking into the aperture for the reception of the frames, and thus destroying the lower frame work; and in addition to this evil, when the windows are down, they are apt to swell, and stick, so rthat they canf not be drawn up. To obviate these diiiiculties the arms have been made solid, to protect the lower frame work; but a serious vdiiiiculty presented itself in the height, and

consequent weight required in the top, to enable the frames to slide up so as not to obstruct the View, thus carrying the body up nine or ten inches higher than when the windows-slide down, which causes the body to give way sooner, as well as adds to its Weight. To obviate these difficulties we form our window frames intwo or more parts which slide up and down 1n separate grooves aS shown 1n the drawings, the lower `frame (a) being the innermost one and having a projecting ledge (b), at the top on its outside, that is on a line with ya similar one (c) on the lower edge of the neXt frame (al) above, like the commonly constructed win dow frames in houses, but in addition to this, we forma projecti-ng ledge (e) on the top of the upper frame on the inside, against which the ledge (b) on the lower frame strikes when raised and carries up the second frame with it, as shown in Fig. 4. Thus it will beL seen, that by taking holdy of the knob, attached to the lower frame and raisingit, all that are above are carried up, and when that is lowered, those above are made to slide down to their places. A window can thus be formed of any given height, which .will slide up into the smallest desired spaces, without any more inconvenience than a single frame. It will be evident that blinds can also be arranged on the same principle.

To prevent the shaking of the windows, we attach to the four corners of each of the frames a light spring (f) on the inside, that bears against the inner face of the groove in which the frame slides. It has been usual to place springs at the edges of the frames but'that will not prevent the jar, which is effectually remedied by our improved application of them to the side.

Having thus fully described our improve--
